Witchcraft: See how Hollywood tricks your eyes with special effects

Tom Cruise runs at full speed, climbs a moving train, duels against an enemy on the edge of a cliff, and escapes unharmed by throwing himself into the sea as the wagon crashes into a rock and explodes. As much as actors seem to have supernatural powers on camera, the reality, unfortunately (or fortunately) is not quite so.

This "witchcraft" has as its tool the special effects employed on a large scale in Hollywood-produced films. But how is this done, and how is a scenario built to make it happen? The selection of images you see below shows that reality is far more bland than fiction. Do you imagine it was anyway?
